Over the years, I have heard many objections to apologetics from Christians. Some of the comments I have heard are:
“We just need to love people.”
“We just need to preach the Gospel.”
“We need to just give people the Word of God.”
” We need to let people see our good deeds.”
I could go on. What I love is that Tim Keller addresses the issue in his article here. He says:
“Apologetics is an answer to the “why” question after you’ve already given people an answer to the “what” question. The what question, of course, is “What is the gospel?” But when you call people to believe in the gospel and they ask, “Why should I believe that?” —then you need apologetics.
I’ve heard plenty of Christians try to answer the why question by going back to the what. “You have to believe because Jesus is the Son of God.” But that’s answering the why with more what. Increasingly we live in a time in which you can’t avoid the why question. Just giving the what (for example, a vivid gospel presentation) worked in the days when the cultural institutions created an environment in which Christianity just felt true or at least honorable. But in a post-Christendom society, in the marketplace of ideas, you have to explain why this is true, or people will just dismiss it.
There are plenty of Christians today who nevertheless say: “Don’t do apologetics, just expound the Word of God—preach and the power of the Word will strike people.” Others argue that “belonging comes before believing.” They say apologetics is a rational, Enlightenment approach, not a biblical one. People need to be brought into a community where they can see our love and our deeds, experience worship, have their imaginations captured, and faith will become credible to them.
There is a certain merit to these arguments. It would indeed be overly rationalistic to say that we can prove Christianity so that any rational person would have to believe it. In fact, it dishonors the sovereignty of God by bowing to our autonomous human reason. Community and worship are important, because people come to conviction through a combination of heart and mind, a sense of need, thinking things out intellectually, and seeing it in community. But I have also seen many skeptics brought into a warm Christian community and yet still ask, “But why should I believe you and not an atheist or a Muslim?”
